This is not possible directly through dbfawk.  The dbfawk language is limited
to setting a few specific internal rendering variables based on the contents 
of the DBF file, and there's no way to *read* xastir internals such as zoom 
level from a dbfawk file, only *set* them.  To accomplish what you want through
dbfawk alone would require enhancements to the dbfawk language.

Yeah, hokey, but a usable workaround given dbfawk's limitations.
